Help Wanted! ModuleNotFoundError: No module named 'sklearn.cross_validation'

marctheshark3 commented 6 years ago

I am using most up to data Mac OS. Not sure where I am going wrong. pip and numpy are both up to date. Also when I try the command suggested:

" nosetests -v sknn "

for the test it gives me these errors:

Traceback (most recent call last): File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/nose/failure.py", line 39, in runTest raise self.exc_val.with_traceback(self.tb) File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/nose/loader.py", line 418, in loadTestsFromName addr.filename, addr.module) File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/nose/importer.py", line 47, in importFromPath return self.importFromDir(dir_path, fqname) File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/nose/importer.py", line 94, in importFromDir mod = load_module(part_fqname, fh, filename, desc) File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/imp.py", line 245, in load_module return load_package(name, filename) File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/imp.py", line 217, in load_package return _load(spec) File "", line 684, in _load File "", line 665, in _load_unlocked File "", line 678, in exec_module File "", line 219, in _call_with_frames_removed File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/sknn/tests/init.py", line 1, in from sknn.backend import lasagne File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/sknn/backend/lasagne/init.py", line 5, in from .mlp import MultiLayerPerceptronBackend File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/sknn/backend/lasagne/mlp.py", line 22, in import sklearn.cross_validation ModuleNotFoundError: No module named 'sklearn.cross_validation'

Ran 1 test in 0.005s

FAILED (errors=2)

I also used the optional method with no luck

So if someone could help me out so I can use scikit-neuralnetwork.

Thank you!

Hi! I think that the sklearn.cross_validation module is deprecated, and replaced by the sklearn.model_selection module in the newer scikit-learn versions, you could create a pull-request after correcting this in mlp.py.

Same problem here :

ModuleNotFoundError Traceback (most recent call last)
